"Late-preterm" infants: a population at risk

Area of Science:

• Neonatal Medicine
• Perinatal Health
• Infant Development

Background:

• Late-preterm infants (34-36 weeks gestation) exhibit reduced physiological and metabolic maturity compared to full-term infants.
• These infants are recognized to have a higher incidence of morbidity and mortality than their full-term counterparts.
• Current terminology like "near term" may not adequately convey the unique risks associated with this gestational age.

Purpose of the Study:

• To establish a clear definition for "late preterm" infants.
• To recommend a standardized terminology, replacing "near term" with "late preterm."
• To delineate characteristics predisposing late-preterm infants to increased health risks and propose evidence-based management guidelines.

Main Methods:

• Literature review and synthesis of existing research on late-preterm infant outcomes.
• Analysis of physiological and metabolic characteristics differentiating late-preterm from term infants.
• Development of clinical guidelines based on identified risk factors and current best practices.

Main Results:

• Late-preterm infants possess distinct developmental immaturities increasing their susceptibility to complications.
• Specific risk factors contributing to higher morbidity and mortality rates have been identified.
• The proposed guidelines offer a framework for consistent evaluation and management.

Conclusions:

• Adopting the term "late preterm" improves clarity and recognition of this population's unique needs.
• Early identification of risk factors and appropriate postnatal care are crucial for improving outcomes.
• Standardized management protocols can mitigate the increased risks faced by late-preterm infants.
